Industrial Processing Equipment

Steel is a time tested material which has proven to be very effective for belt ovens. The main use for Steel Belt Ovens is biscuits/cookies, however, they can also be used for pies, pastries and even some pet food products.

Steel belts are often exposed to extreme mechanical and thermal stress. For this reason it is important to purchase your steel belt oven from a reputable manufacture who you know will provide steel that will withstand these extreme conditions. Process Systems Services Pty Ltd manufactures the highest quality steel belt ovens.

Hygiene advantages of Steel Belt Ovens

Steel belt ovens are primarily used in the food processing industry; this is due to its high hygiene level.  Steel has a completely flat, smooth surface; this means that it does not have any crevices for dirt and other foreign particles to lodge into. Steels hardness and durability enables for easy and efficient cleaning of all surfaces with a variety of different cleaning methods such as heat, scrubbing, high pressure sprays and chemicals. Additionally, the hard surface makes it more durable and therefore your oven will have a much longer life-span. Steel is not able of absorbing bacteria in the way that other, more natural materials are, for example, wood. A lot of foods contain acid which have a tendency to cause pitting which creates the perfect environment for bacteria to grow and bread. Steel is not affected by acid and therefore does not and therefore avoids this problem and is ideal for cooking acidic foods. When all these things are taken into consideration it is clear that steel belts is the most hygiene option for industrial ovens.

Pneumatics

Pneumatics is the use of pressurised gas to create mechanical motion. The English word pneumatic dates from 1659, and is derived from the French pneumatique, derived from the Latin word pneumaticus meaning ‘wind’, from the Greek word pneumatikos (meaning ‘breath’, ’spirit’, ‘ethereal’), from the Greek pneuma(current of air, breath, breeze, spirit). This was originally taken from the Proto-Indo-European root pneu (to breathe).

Pneumatic power has many uses from air brakes on buses, to anti-aircraft weapons, pipe organs, pneumatic tools, vacuum pumps, pressure sensors and so on. Different gases in pneumatic systems are depending on where and how they are used. For example, portable tools and hobbyist applications are often powered by compressed carbon dioxide because the containers designed to hold it are readily available. Whereas pneumatic systemsin fized installations often use compressed air because a sustainable supply is possible through compressing atmospheric air. The air usually has the moisture removed and a small amount of oil added to lubricate and avoid corrosion of mechanical components.

Pneumatic Conveying

Using a pneumatic conveyor has many advantages. First of all, the controls are usually quite simple to operate. Secondly, they are very reliable. Pneumatic systems require very little maintenance since the equipment is less likely to be damaged by shock. While fluid will directly transfer force, the gas in pneumatics absorbs excessive force. Another advantage is that compressed gas can be stored, meaning the conveyor could potentially be used even in power black outs.

Finally, pneumatic systems are quite safe when using compressed atmospheric air (other compressed gases carry the risk of asphyxiation if released). Compressed gas has a low chance of fire compared to hydraulics (compressed oxygen is never used to the extreme fire hazard), and machines can be designed to be overload safe.

Process System Services Pty Ltd offers a range of pneumatic conveying systems, including lean phase and dense phase systems for transporting materials such as powders, granules, grains or flakes.

Uses for Commercial Ovens

Commercial ovens are primarily used for baking, a process of prolonged cooking by dry heat through convection. It is usually used for cooking baked goods such as bread, cookies, cakes, pies, pastries and so on. However it can also ovens can also be used to prepare vegetables, meats, casseroles, deserts, pasta dishes and other foods. Of course, ovens can also be used to bake other things such slurries of minerals, pet food, and pharmaceuticals.

Many commercial ovens are designed with different heating elements, one using convection to bake, conduction to heat and radiation to grill. Some food preparation requires a combination of these heating elements. One of the advantages to baking products is that the process does not add any fat to the product, as opposed to processes such as deep-frying.

Types of Ovens

Ovenscan be heated by different means. There are conduction systems, which involve the transfer of thermal energy between neighbouring molecules to equalise temperature differences, and convection systems which uses a fan to expose the food to hot air flows. Then there are infrared ovens which heat opaque and absorbent objects rather than the air around it. Microwaves are another method of cooking food. Microwaves as a technique for cooking food was discovered by accident by Percy Spencer in the 1940s while building magnetrons for radar sets.

A microwave oven cooks by using microwave radiation to heat water and other polarised molecules such as fat within food. Microwaves are a frequency between radio and infrared frequencies, usually ar around 2.5 gigahertz. Microwaves cook through dielectric heating. This is when molecules that have a positive charge at one end and a negative charge at the other, rotate as they try to align themselves with the alternating electric field of the microwaves. This molecular movement represents heat that is then dispersed as the rotating molecules hit other molecules, putting them into motion.
